Given numbers are 398,438,964,964
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,438,964,964 is 42012084.
Find LCM of 398,438,964,964 with Prime Factorization
| 2 | 398, 438, 964, 964 |
| 2 | 199, 219, 482, 482 |
| 241 | 199, 219, 241, 241 |
| 199, 219, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 241 x 199 x 219 x 1 x 1 = 42012084
Therefore, the lowest common multiple of 398,438,964,964 is 42012084.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
398 x 438 x 964 x 964 = 161998595904
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
398 : 1, 2, 199, 398
438 : 1, 2, 3, 6, 73, 146, 219, 438
964 : 1, 2, 4, 241, 482, 964
964 : 1, 2, 4, 241, 482, 964
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,438,964,964, is 2.
Now, the common factors can be found like this.
398:2x 199
438:2x 3x 73
964:2x 2x 241
964:2x 2x 241
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 241 = 1928
Therefore, the value for common factors is 1928.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 161998595904/(2x1928)
LCM = 161998595904/3856
LCM = 42012084
Thus, we can understand that the LCM of 398,438,964,964 is 42012084.
